A recent paper published in the Journal of Clinical Oncology updated the outcomes of multiple myeloma trials conducted by the Intergroupe Francophone du Myelome, the Southwest Oncology Group, and the University of Arkansas for Medical Sciences.
The update provides a fuller, long-term picture of the advantages of some of the autotransplant regimens being tested. It represents the first international effort at systematically updating previously reported trial results, which had indicated that autotransplantation with high-dose melphalan (Alkeran) therapy significantly extends the survival of multiple myeloma patients.
Autologous stem cell transplantation, or autotransplantation, is a…
The use of thalidomide (Thalomid) in induction and maintenance therapies for multiple myeloma patients receiving a stem cell transplant resulted in better overall response rates but did not significantly improve overall survival, according to a Phase 3 study recently published in the journal Blood.
In their study, researchers randomly assigned 556 patients to receive three cycles of either vincristine (Oncovin), doxorubicin, and dexamethasone [VAD] or thalidomide, doxorubicin (Adriamycin), and dexamethasone (Decadron) [TAD] as induction therapy. All patients received high-dose melphalan (Alkeran) with an autologous stem cell transplant, followed by maintenance therapy with either alpha-interferon for patients…
A recent study published in the Journal of Clinical Oncology determined that patients who achieved very good partial response (VGPR) or better after high-dose chemotherapy and stem cell transplantation experienced significantly longer event-free and overall survival.
“Very good partial response” is one of the terms defined by the International Myeloma Working Group (IMWG) to categorize how patients respond to treatment. According to IMWG criteria (see related Beacon news), patients reach very good partial response when the level of abnormal “M” proteins in their blood decreases by 90 percent.

Dacetuzumab Shows Some Potential For Multiple Myeloma – Results from a Phase 1 clinical trial show that dacetuzumab (SGN-40), an anti-CD40 monoclonal antibody, has some anti-myeloma effects. The best response observed during the trial was stable disease in 20 percent of patients. The study authors found that doses up to 12 mg/kg per week were well tolerated. Most side effects were mild to moderate and included fatigue, headache, nausea, and anemia. The study authors suggest that dacetuzumab may produce better response rates in combination with other myeloma drugs. Two combination trials (one with Revlimid (lenalidomide) and one with Velcade (bortezomib)) are underway. For more information, please see the study in The Haematologica Journal (pdf) and the clinical trial descriptions (dacetuzumab with Revlimid or Velcade) .
Myeloma Awareness Month Teleconference Series – Each Friday during the month of March, the International Myeloma Foundation (IMF) will be hosting a teleconference to raise awareness and provide up-to-date information about multiple myeloma. The teleconferences are scheduled for 7 p.m. EST and will include a 60 minute presentation followed by a 30 minute Q&A. Patients, family members, caregivers, and health care professionals are welcome to join. Please see the IMF Web site for more information.
NCI Designs MGUS/Smoldering Myeloma Study – Researchers from the National Cancer Institute (NCI) are in the process of developing a prospective study with the goal of identifying causes of transformation from monoclonal gammopathy of undetermined significance (MGUS) and smoldering myeloma (both asymptomatic, pre-malignant disorders) to multiple myeloma. The study will enroll 350 patients with MGUS or smoldering myeloma in the United States and follow them for up to five years. For more information, please contact the research nurse for this study, Mary Ann Yancey, at (301) 435-9227 or yanceym@mail.nih.gov.

Patients who do not respond at least partially to treatment with Revlimid (lenalidomide) or thalidomide (Thalomid) prior to a stem cell transplant may have significantly shorter survival times, according to a recent study published in the journal Blood.
Currently, the standard treatment plan involving stem cell transplantation begins with induction therapy, which decreases the number of abnormal cells and proteins in a patient’s bone marrow before collection of stem cells for the transplant. Next, patients undergo high-dose chemotherapy and transplantation, after which, some patients receive consolidation or maintenance therapy.
